moving to new domain and duplicated content

I am moving 160 pages to new domain.
I will redirect those old pages from old domain to new one.

Text surely will be the same, just redirection.

Could google recognize this new pages as duplicated content ?

 

If you are using a 301 redirect from each of the old urls to the page's new url you should be ok.

Expect some loss of ranking and traffic for a short period of time but other than that it works well.

 

Can I leave text on old URLs or I must erase this text ?

The same text will be on new URL.

 

It's ok as long as you leave the 301 redirect in place. If it was me I would take the pages completed down after 6 months and then have it return a 410 (page deleted) after that.

 

Thanks!

Other opinions ?

 

I agree with classifieds - as long as you use 301 redirects, you should be fine. If you're not sure when you should delete the old pages, you can always take a look at the SERPs, and wait until they're no longer listed (or all of your new pages are listed) to delete them.

HTH,

Thanks!
That with deleting pages sounds very smart.
